Application filed August 16, 1900. Serial No. 27,074. (No model.)

T0 at whont it may concern.-

Be it known that I, FRANZ FORTELKA, a citizen of the Empire of Austria-Hungary, residing at Vienna, in the Province of Lower Austria, in the Empire of Austria-Hu-ngary, have invented certain new and useful Improvements in Magazines for Firearms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of; this-specification. r My invention relates tomagazine-firearms, and has for its object the construction of a drum-shaped magazine situated underneath the breech-receiver and containingasmaller central spring-rotated drum around which the cartridges are placed, said inner drum having a feeding-web, by means of which the cartridges are brought in succession to the feeding-chamber of the receiver. 4

In the annexed drawings a magazine of this kind is shown, of which-- Figure l isa longitudinaland Fig. 2 a transverse section.

In both figures similar letters of reference indicate corresponding parts.

The lower part of the breech-receiver is formed into a conical or cylindrical drum or casing'a, in the mathematical line of axis of which a pin or shaft b is situated. Upon this pin b is placed the rotaryinner drum d. Inside this drum d and upon the pin bis placed a helical spring 0, the one end of which is fastlened to the pin b and the other to the drum web f, which is shaped to correspond to the form of the cartridges and which moves in the space between the inner and outer drums.

The drum ct is open at its top part and communicates with the breech-receiver, in which is guided the breech-bolt g. This communi-- cating opening between'the magazine and the receiveris' closed ofi on one side by a partition it. Opposite this partition 71 a spring is attached to the interior surface of the drum a, which is also provided with a recess 1', into which the spring is may enter when it is do pressed. This spring 10 serves for holding in The drum d is provided with a 'fe'eding-= place the cartridge already entered .into the receiver and the cartridge next to it in the magazine.

When the magazine-is empty, the feederf stands opposite the partition h in the position indicated by dotted lines in Fig. 2. The'lnagazinc is charged by pushing one cartridge after the other through the breech-receiver into the drum a, each cartridge passing underneath the retaining-spring It. By the introduction of the cartridges in, this manner the drum d, with the feeder f, is turned in a direction opposite to the direction of the force exerted by When the magazine is filled with cartridges, the feederfstands facing the inner side of the partition h, as shown in Fig. 2. After the first cart-ridge placed into the receiver has been fired and ejected the next cartridge in the magazine passes underneath the spring itinto the receiver, from whence'it is pushed into the firing-chamber by the breech-bolt, while the next cartridge is retained in the magazine by the spring 10'. This operation may be continued until the magazine has been.

emptied.
